I think it is because of air resistance. Think about it, when objects fly up in the atmosphere they still must get past the air molecules floating around. The rocket tips being sharper allows the rocket to "slice" in between the molecules, which makes the rocket fly faster and easier. If the top was flat, the rocket would have to "push" the molecules out of the way, which would slow the rocket down.
A teardrop is the most aerodynamically effective shape for a rocket travelling through the atmosphere. From an engineering standpoint, a cylindrical shape accommodates compressed gas cylinders (fuel and oxygen) most efficiently. For a rocket operating outside the atmosphere, shape is irrelevant because it will not encounter drag no matter how un-aerodynamic the shape.
The hypothesis for a balloon rocket is whether the shape of the balloon will affect the distance that it will travel.
a rocket ship is sort of shaped like a bullet with 3 different parts the botom 2 fall off
Gravity is the biggest determining factor of the direction of motion of a vessel in orbit, and the rocket's engines are used to change the shape of that orbit.
no
No but if it is pointed straight up, it will take less fuel.
rounded
so it is streamlined

Yes, so that it is more streamlined.
heptagon
pentagon
No, vertices do not have to be pointed out. Vertices are the points where the edges of a shape or object meet. They can be sharp or rounded, depending on the shape or object.
is there any??the only 5 pointed star i know is the shape
The best shape of a rocket is a cylinder with a cone at the top, because that form penetrates easily trough the wind!
A cone on top of a cylinder.
